ANTIFBICTION 'BEARING.

. This invention relates to anti-friction An object of the invention is to provide a simple, practical, relatively inexpensive bearing, especially adapted for railway car side bearings, in which the parts are so arranged that the anti-friction elements are automatically returned to the normal centered position when free from load.

Another object ofthe invention is to provide a sidebearing of this character including a retainer adapted to be disposed. upon the truck bolster of a railway car and having anti-friction means disposed therein and adapted to move to and fro'with reference to said mounting, in conjunction with transmitting elements slidably associated with the mounting and arranged to bear upon the outer sides of tlie anti-friction means above the central axis thereof, together with resilient. means connecting said transmitting members, whereby movement of the antifrictionmeans to one side of the other of central position carries one of said transmitting members therewith while the other is held relatively fixed, thereby stretching the resilient means so that the reactive force operates to return the anti-friction means to central position, and to maintain the same in assembled relation with said mounting when free from load. v V

' Other and further objects of the invention will morefully and clearly appear'fro'mthe description and claims hereinafter followlIl Tn the drawing forminga part of this specification, Fig. 1 is a vertical, sectional viewtaken through the ends of the body and truck bolsters of a railway car, showing my invention in connection therewlthi Fig. 2

is a top plan view of the antifriction hearing, showing my improvements in connection therewith. [And Fig. 3 is avertical sectional'view' through the anti-friction bearing detached from the truck bolster, and

showing a slightly diiferentxembodiment of my invention.

Referring tofFigs. 1 and 2 of the drawings, lO indicatesthe underside of a body bolster, and 11 the upperside of the corresponding truck bolsterof a railway car.

plied to the truck bolster and comprises :My improved side bearing is shown as ap-' broadly, a housin or retainer anti-friction elements -B transmitting elements CC; and resilient means DD.

, The housingA is preferably of rectangular formation provided with curved end walls 13-43, vertically disposed side walls 14c l 4, andwitha bottom 15, said bottom being provided with recesses .16 for thereception of' the heads of rivets 17-17, which serve to secure the bearing plate 18 to the bottom wall 15 of thehousing A. The housing A is provided at its low'er'end portionsjwlth securing flanges 1919 through which extend securing rivets 2020 which secure the housing to-the truck bolster. The sidewalls 1 2-1 1 extend beyond the lower portions of the curvedv end walls 13 -13 to provide strengthening webs 2l.21. i

Each of the side walls'l, of the housing A is provided with an elongated'horiz'ontally disposed slot 22'a'dj acent one end portion of said side wall, and adjacent thetop edge thereof, and is provided at the opposite v end portion thereof with a similarly arranged 3 elongated slot 23. Each of said side walls is also provided with a centrally disposed elongated slot 24 arranged adjacent thetop.

edge of the side Wall in substantiallythe same plane as the slots 22-and23.

Disposed in the housing Aa'nd adapted to move back. and forth. upon 'the' bearing plate 18 are anti-friction mean's,l'which as shown. comprise two cylindrical rollers I The transmitting membersC C are two in number,':one of the same being disposed.

outside of one of the anti-friction elements B, and the other being disposed uponthe opposite side of the other of the anti-friction ele- 1 ments B, each of said transmitting members C being in the form of an elongated. cylindrical pin having its opposite ends project- 'ing outwardly through the slots 22' and 23 in'the side walls, as indicated at 24, and the outer ends of the transmitting members CC have connected therewith theresilient means The resilient means DD are two ingnu me oer, one of the samev being disposed on each i 7 side of the housing A and ext-eriorally of the side wall thereof, and each has its opposite ends connected to the adjacent ends offthetransmitting members CC which project Chi said holes being sloped to 'induce'a flow of oil in opposite directions.

What I claim is: V

1. In a bearing, the combination of two relatively rotatable coaxial members, one of said members being provided with a lubricant reservoir or chamber, the Wall of'said last named member being pierced'with holes I communicating with said reservoir and with the bearing surface between saidmembers, said holes being oppositely inclined respectively to radii to the axis of said membersto induce ajflow of lubricant to and from said reservoir. i

"2. In a bearing, the combination of two relatively rotatable coaxial'members, one of said members being provided with a lubricant reservoir 01' chamber, the wall of said last named member being pierced with holes c'ommunlcatlng withsaid reservo r and with the bearing'surface between said members,

said holesbeing; oppositely inclined respectivel to radii to the axis of said members 111 p anes perpendicular to said axis to induce aflow of lubricantyto and'gfrom said reservoir. i 4 Y 3. In abearing, the combination of "two relatively rotatablecoaxial members, one of I said members being provided with a lubricant reservoir or chamber,the wall of said last named member being pierced: with holes communicatlng with said reservoir and with I the bearing surface between said members,

said holes being oppositely inclined 'respec- 'tively to radii to the axis of said members, and spaced'longitudinally of said axis to ini :duce a fi'ow of lubricantto and from said reservolr and longitudinally over sa d surface.

tion displaces one of said transmitting mem mitting element, will serve to return the element toward central position. A like action occurs upon movement of the anti-friction element B in the opposite direction as will be understood.

' the slots of said side walls; coiled springs connecting the opposite end portions of said transmitting members; and anti-friction means disposed in said housing and arranged between said transmitting members.

2. In an anti-friction bearing, the, combi nation with a retainer; of anti-friction means mounted in said retainer and adapted to move back and forth with respect thereto; movable transmitting members arranged at opposite sides of said anti-friction means in the path thereof; means limiting inward movement of said transmitting members toward each other; and spring means conmeeting said transmitting members whereby movement of said anti-friction in one direchers to stretch said spring means, whilethe remaining member is held against move- 'ment, and movement of said anti-friction means in another direction displaces the other transmitting member to stretch said sprmgmeans 1n the same manner, sald spring means operating in each instance to return the anti-friction means to central position.

8. In an anti-friction bearing of thecharact-er described, the combination with a re-' tainer having side walls provided with spaced longitudinally extending slots; of anti-friction means adapted to move back and forth withreference to said retainer;

- a central slot arranged intermediate of sai end slots; a plurality of anti-friction ele-' movement;

transmitting members extending transversely of said housing and having their opposite end portions slidably mounted in said slots; and tension springs arranged outwardly ofthe side walls of-the said retainer and each having its opposite ends connected 1 to the adjacent ends of said transmitting members. 1

e. In an ant1-fr1ction bearing of the character described, the comblnation with ahousinghaving side walls each of which'is' provided with spaced horizontally disposed I slots adjacent the opposite ends thereof, and

ments disposed in said housing andarranged to move back and forth with respect thereto; transmitting members disposed atthe outer sides of said anti-friction elements in the path thereof, said transmitting members being slidably mounted in the slots in said side walls; a retainer member interposed be tween said anti-friction elements and slidably mounted in said central slots; and resilient means connecting said transmitting ,members for yieldably urging said anti-friction elements toward normal central position.

5. In an anti-friction bearing, the combi-v nation with a retainer; of a plurality of anti.- friction elements adapted to move back and forth to either-side of central position with respect to said'retainer; transmitting members disposed at the outer sides of said antifriction elements and engaging the same above the central axes thereof, said transmitting members being movable horizontally v and restrained against vertical movement; resilient means normally urging said transmitting members into engagement with said anti-friction elements; and aretaining mem ber interposed between said anti-friction elements and above, the axial centers thereof and being mounted to have movement in the direction of movement of said anti-frio tion elements and restrained from-vertical In witness that I claim the foregoing 'I have hereunto subscribedmy name this3rd day of February, 1926. 1 p
